1 Claim.

This invention relates to an improved float controlled valve.

The object of the valve contained in a receptacle to control the outlet pipe communicating with said receptacle so that the pipe will be automatically closed when the liquid in the receptacle reaches a predetermined point.

A further object of the invention is to provide valve means whereby an outlet pipe will be shut oi when the level o falls below a certain f the liquid in a container point, to prevent air entering said container through said pipe.

Other objects and advantages of the invention will become apparent from the specification of which the drawings form a part, and wherein:

Figure 1 is a side elevational view of the invention contained in the receptacle which is shown in section,

Figure 2 is a fragmentary sectional view in side elevation showing the valve means,

Figure 3 is a cross sectional view of the same on the line 3-3 of Figure 1,

Figure 4 is a view similar to Figure l of a modied means to control the valve,

Figure 5 is a View similar to Figure 2 showing the modified form, and

Figure 6 is a view the modied form.

similar to Figure 3 showing An outlet pipe I3 and has a casing I4 extends into receptacle |10 mounted thereon. Casing I4 is hollow and contains corresponding recesses I5 and I6 which are I1 and a horizontal separated by vertical walls wall I8. A valve seat I9 formed in wall I8 forms a passage between recesses I5 and I6 and receptacle I0 and pipe I3.

Casing I4 is provided with an annular internally threaded flange 20 into which is secured a threaded plug 2I provided with abore 22. Flange with a pointed end'25 forming the is adapted to engage pipe I3. adapted to limit the Stem 24 is provided with a pin spaced openings 23 which recess I6. A valve stem 24 in bore 22 and is provided valvev which I9 to shut off 26 the valve seat movement of stem 24.

A weight 21 is secured to the lower end oi valve stem 24 by means of a pin 28 which extends through an opening in the weight 21 and invention is to provide a in the stem 24 to normally hold valve 25 in an open position.

A pair of pulleys 29 are journaled in hangers 30 which are secured to the top of Areceptacle I0.

A cable 3| engages pulleys 29 and has a oat 32 5 secured to one end thereof. The opposite end of cable 3| is secured to a U-shaped hanger 33. The opposite ends of hanger 33 are connected to eyelets 34 secured to weight 21.

Figures 4A 5 and 6 illustrate a modication of 10 the invention, wherein a cross head 34 is secured to the end of stem 24 and a coil spring 35 is mounted on stem 24 between plug 2I and cross head 34 to normally urge stem 24 downwardly.

Float 32 is secured to one end of a lever 36 15 which is pivoted to a bracket 31 mounted on casing I4. The opposite end of lever 36 is connected to rod 38 which is also connected by bolt 39 to cross head 34.

A ball valve 49 is mounted in a cage 4I formed 20 of four vertical rods forming guides. Valve 49 is a one way valve and is adapted to close opening I9 from above to prevent liquid flowing from pipe I3 back into tank I0 in case the pressure in pipe I3 becomes greater than the pressure in 25 tank I0. The flow from tank I0 to pipe I3 will raise valve 40.

In operation, when the liquid level in receptacle I0 falls below a certain point iioat 32 will lift weight 21 or cross head 34 causing valve 25 to 30 move upwardly and engage valve seat I9 shutting oi pipe I3 to prevent air entering the tank I0. As the liquid level rises float 32 will move upwardly permitting weight 21 or spring 35 to draw valve 25 downwardlyto permit the liquid II to 35 pass out through pipe I3.

It is to be understood that only the preferred embodiment of the invention has been shown, the right being reserved to make such changes and modifications as will not depart from the 40 spirit and scope of the invention as claimed.

I claim as my invention:

In combination with a liquid storage tank provided with inlet and outlet pipes, a casing having oppositely disposed open ends, a partition disposed longitudinally within said casing between said ends and including a longitudinally disposed intermediate portion provided with a vertical passage, said casing'having a depending open end disposed beneath said intermediate portion, a plug removably mounted in said depending end and provided with a longitudinal bore disposed in alinement with said passage, a needle valve slidably mounted in said bore, one end of said needle valve being tapered to seat in and close end thereof, a. oat mounted in said tank and connected to said abutment and adapted to be actuated by the level of a liquid contained therein for closing the valve against the action olf said spring, and a gravity actuated valve mounted in f' the rst mentioned end of said casing and adapted for seating in the upper end of said passage.
